In the first half of the twentieth century the Marbled Godwit (Limosa fedoa) was considered a rare species in Washington (Jewett et al. 1953). Its status has changed since that time, and it is now locally common in migration and winter in coastal Washington (Buchanan 2005). The extension of the winter distribution is particularly unusual in that the new range is substantially north of the species’ contiguous range in central California and also well north of isolated areas of winter occurrence in northern California and southern Oregon (Gratto-Travor 2000). In this paper I present data that illustrate a change in the Marbled Godwit’s abundance during winter in coastal Washington over the last several decades.
